MYB Transcription Factor Family
The cloning of the first transcription factor from plants, the C1 gene of maize, indicated that plants use transcription
factors that are structurally related to those of animals in their control of gene expression, because C1 showed significant
structural homology to the vertebrate cellular proto-oncogene c-MYB. Since 1987, the catalogue of MYB-related transcription
factors has increased considerably in size due, primarily, to the ever-expanding number of MYB genes identified in higher
plants (Arabidopsis thaliana is estimated to contain more than a hundred MYB genes). In vertebrates, the MYB-related
proto-oncogenes comprise a small family with a central role in controlling cellular proliferation and commitment to
development. However, while the functions of some plant MYB genes are relatively well understood they are, at present, quite
distinct from their animal counterparts.
343 predicated puattive TFs contain MYB domain peptide,
CDS, and cDNA sequences,
blast HSP.
300+ MYB domain peptide sequences with
alignment and phylogeny tree.
74 MYB protein
and
DNAsequences
with
annotations for soybean in PlantTFDB. Most are partial sequences.
